FAQ

ZyNOS FAQ

1 What is ZyNOS

ZyNOS is ZyXELs proprietary Network Operating System It is the platform on

all Prestige routers that delivers network services and applications It is

designed in a modular fashion so it is easy for developers to add new features

New ZyNOS software upgrades can be easily downloaded from our FTP sites

as they become available

2 Whatrsquos Multilingual Embedded Web Configurator

Multilinggual Embedded Web Configurator means that it can display with 3

kinds of languanges English French and German By factory default it

displays with English and you can change it in Web GUI

3 How do I access the P-660HW-Dx v2 Command Line Interface (CLI)

The Command Line Interface is for the Administrator use only and it could be

accessed via telnet session

Note It is protected by super password lsquo1234rsquo by factory default

4 How do I update the firmware and configuration file

You can do this if you access the P-660HW-Dx v2 as Administrator You can

upload the firmware and configuration file to Prestige from Web Condigurator

or using FTP or TFTP client software You CAN NOT upload the firmware and

configuration file via Telnet because the Telnet connection will be dropped

during uploading the firmware Please do not power off the router right after the

FTP or TFTP uploading is finished the router will upload the firmware to its

flash at this moment

Note There may be firmware that could not be upgraded from Web

Configurator In this case ZyXEL will prepare special Upload Software

for you Please read the firmware release note carefully when you want to

upload a new fireware


program via LAN

The P-660HW-Dx v2 allows you to transfer the firmware to P-660HW-Dx v2

using TFTP program via LAN The procedure for uploading ZyNOS via TFTP

is as follows

9 What is SUA When should I use SUA

SUA (Single User Account) is a unique feature supported by Prestige router

which allows multiple people to access Internet concurrently for the cost of a

single user account

When Prestige acting as SUA receives a packet from a local client destined for

the outside Internet it replaces the source address in the IP packet header

with its own address and the source port in the TCP or UDP header with

another value chosen out of a local pool It then recomputes the appropriate

header checksums and forwards the packet to the Internet as if it is originated

from Prestige using the IP address assigned by ISP When reply packets from

the external Internet are received by Prestige the original IP source address

and TCPUDP source port numbers are written into the destination fields of the

packet (since it is now moving in the opposite direction) the checksums are

recomputed and the packet is delivered to its true destination This is because

SUA keeps a table of the IP addresses and port numbers of the local systems

currently using it

10 What is the difference between SUA and Full Feature NAT

When you edit a remote node in Web Configurator Advanced Setup Network

-gt Remote Node -gt Edit there will be three options for you

None

SUA Only

Full Feature

SUA (Single User Account) in previous ZyNOS versions is a NAT set with 2

rules Many-to-One and Server With SUA visible servers had to be mapped

to different ports since the servers share only one global IP

The P-660HW-Dx v2 now has Full Feature NAT which supports five types of

IPPort mapping One to One Many to One Many to Many Overload Many to

Many No Overload and Server You can make special application when you

select Full Feature NAT For example With multiple global IP addresses

multiple severs using the same port (eg FTP servers using port 2120) are

allowed on the LAN for outside access

The P-660HW-Dx v2 supports NAT sets on a remote node basis They are

reusable but only one set is allowed for each remote node The P-660HW-Dx

v2 supports 8 sets since there are 8 remote nodes

By fatory default the NAT is select as SUA in Web Configurator Advanced

Setup Network -gt NAT -gt General -gt NAT Setup



8


Internet How can I do it

Yes it is possible because P-660HW-Dx v2 delivers the packet to the local

server by looking up to a SUA server table Therefore to make a local server

accessible to the outside users the port number and the inside IP address of

the server must be configured (You can configure it in Web Configurator

Advanced Setup Network -gt NAT -gt Port Forwarding)

12 When do I need select Full Feature NAT

Make multiple local servers on the LAN accessible from outside with

multiple global IP addresses

With SUA visible servers had to be mapped to different ports since the

servers share only one global IP But when you select Full Feature you can

make multiple local servers (mapping the same port or not) on the LAN

accessible from outside with multiple global IP addresses

Support Non-NAT Friendly Applications

Some servers providing Internet applications such as some MIRC servers do

not allow users to login using the same IP address Thus users on the same

network can not login to the same server simultaneously In this case it is

better to use Many-to-Many No Overload or One-to-One NAT mapping types

thus each user login to the server using a unique global IP address

13 What IPPort mapping does Multi-NAT support

Multi-NAT supports five types of IPport mapping One to One Many to One

Many to Many Overload Many to Many No Overload and Server The details

of the mapping between ILA and IGA are described as below Here we define

the local IP addresses as the Internal Local Addresses (ILA) and the global IP

addresses as the Inside Global Address (IGA)

One to One In One-to-One mode the P-660HW-Dx v2 maps one ILA

to one IGA

Many to One In Many-to-One mode the P-660HW-Dx v2 maps

multiple ILA to one IGA This is equivalent to SUA (ie PAT port

address translation) ZyXELs Single User Account feature that previous

ZyNOS routers supported (the SUA is optional in todays Prestige

routers)

Many to Many Overload In Many-to-Many Overload mode the

P-660HW-Dx v2 maps the multiple ILA to shared IGA



9

Many One-to-One In Many One-to-One mode the P-660HW-Dx v2

maps each ILA to unique IGA

Server In Server mode the P-660HW-Dx v2 maps multiple inside

servers to one global IP address This allows us to specify multiple

servers of different types behind the NAT for outside access Note if

you want to map each server to one unique IGA please use the

One-to-One mode

The following table summarizes the five types

14 How many network users can the SUANAT support

The Prestige does not limit the number of the users but the number of the

sessions The P-660HW-Dx v2 supports 2048 sessions that you can use the

ip nat session command in CLI to see You can also use bdquoip nat hashTable

wanif0‟ to view the current active NAT sessions

15 What are Device filters and Protocol filters

In ZyNOS the filters have been separated into two groups One group is

called device filter group and the other is called protocol filter

group Generic filters belong to the device filter group TCPIP and IPX filters

belong to the protocol filter group You can configure the filter rule in CLI

Note In ZyNOS you can not mix different filter groups in the same filter set



10

16 How can I protect against IP spoofing attacks

The P-660HW-Dx v2s filter sets provide a means to protect against IP

spoofing attacks The basic scheme is as follows

For the input data filter

Deny packets from the outside that claim to be from the inside

Allow everything that is not spoofing us

Filter rule setup

Filter type =TCPIP Filter Rule

Active =Yes

Source IP Addr =abcd

Source IP Mask =wxyz

Action Matched =Drop

Action Not Matched =Forward

Where abcd is an IP address on your local network and wxyz is your

netmask

For the output data filters

Deny bounce back packet

Allow packets that originate from us

Filter rule setup

Filter Type =TCPIP Filter Rule

Active =Yes

Destination IP Addr =abcd

Destination IP Mask =wxyz


Action No Matched =Forward

Product FAQ

1 How can I manage P-660HW-Dx v2

Multilingual Embedded Web GUI for Local and Remote management

CLI (Command-line interface)

Telnet support (Administrator Password Protected ) for remote

configuration change and status monitoring

FTP TFTP sever firmware upgrade and configuration backup and

restore are supported(Administrator Password Protected)

2 What is the default password for Web Configurator

There are two different accounts for P-660HW-Dx v2 Web Configurator

Common User Account and Administrator Account

By factory default the password for the two accounts are

Common User Account user

Administrator Account 1234

You can change the password after you logging in the Web Configurator

Please record your new password whenever you change it The system

will lock you out if you have forgotten your password

3 Whatrsquos the difference between lsquoCommon User Accountrsquo and

lsquoAdministrator Accountrsquo

For Common User Account it can only access the status monitor of

P-660HW-Dx v2 and check the current system status

For Administrator Account besides accessing the status monitor of

P-660HW-Dx v2 it can also access Winzard setup Advanced setup of

P-660HW-Dx v2

Moreover only with Administrator Password you could manage the

P-660HW-Dx v2 via FTPTFTP or Telnet


ISP

You can view My WAN IP ltfrom ISPgt xxxx shown in Web Configurator

bdquoStatus-gtDevice Information -gtWAN Information‟ to check this IP address

5 What is the micro filter or splitter used for

Generally the voice band uses the lower frequency ranging from 0 to 4KHz

while ADSL data transmission uses the higher frequency The micro filter acts



12

as a low-pass filter for your telephone set to ensure that ADSL transmissions

do not interfere with your voice transmissions For the details about how to

connect the micro filter please refer to the users manual


difference between them

When the ISP limits some specific computers to access Internet which means

only the traffic tofrom these computers will be forwarded and the other will be

filtered In this case we use bridge mode which works as an ADSL modem to

connect to the ISP The ISP will generally give one Internet account and limit

only one computer to access the Internet

For most Internet users having multiple computers want to share an Internet

account for Internet access they have to add another Internet sharing device

like a router In this case we use the router mode which works as a general

Router plus an ADSL Modem

7 How do I know I am using PPPoE

PPPoE requires a user account to login to the providers server If you need to

configure a user name and password on your computer to connect to the ISP

you are probably using PPPoE If you are simply connected to the Internet

when you turn on your computer you probably are not You can also check

your ISP or the information sheet given by the ISP Please choose PPPoE as

the encapsulation type in the P-660HW-Dx v2 if the ISP uses PPPoE

8 Why does my provider use PPPoE

PPPoE emulates a familiar Dial-Up connection It allows your ISP to provide

services using their existing network configuration over the broadband

connections Besides PPPoE supports a broad range of existing applications

and service including authentication accounting secure access and

configuration management

9 What is DDNS

The Dynamic DNS service allows you to alias a dynamic IP address to a static

hostname allowing your computer to be more easily accessed from various

locations on the Internet To use the service you must first apply an account

from several free Web servers such as httpwwwdyndnsorg

Without DDNS we always tell the users to use the WAN IP of the

P-660HW-Dx v2 to reach our internal server It is inconvenient for the users if

this IP is dynamic With DDNS supported by the P-660HW-Dx v2 you apply a



13

DNS name (eg wwwzyxelcomtw) for your server (eg Web server) from a

DDNS server The outside users can always access the web server using the

wwwzyxelcomtw regardless of the WAN IP of the P-660HW-Dx v2

When the ISP assigns the P-660HW-Dx v2 a new IP the P-660HW-Dx v2

updates this IP to DDNS server so that the server can update its IP-to-DNS

entry Once the IP-to-DNS table in the DDNS server is updated the DNS

name for your web server (ie wwwzyxelcomtw) is still usable

10 When do I need DDNS service

When you want your internal server to be accessed by using DNS name rather

than using the dynamic IP address we can use the DDNS service The DDNS

server allows to alias a dynamic IP address to a static hostname Whenever

the ISP assigns you a new IP the P-660HW-Dx v2 sends this IP to the DDNS

server for its updates


wildcard

Some DDNS servers support the wildcard feature which allows the hostname

yourhostdyndnsorg to be aliased to the same IP address as

yourhostdyndnsorg This feature is useful when there are multiple servers

inside and you want users to be able to use things such as

wwwyourhostdyndnsorg and still reach your hostname

Yes the P-660HW-Dx v2 supports DDNS wildcard that httpwwwdyndnsorg

supports When using wildcard you simply enter yourhostdyndnsorg in the

Host field in Menu 11 Configure Dynamic DNS


IPSec gateway

Yes the P-660HW-Dx v2s SUA can handle IPSec ESP Tunneling mode We

know when packets go through SUA SUA will change the source IP address

and source port for the host To pass IPSec packets SUA must understand

the ESP packet with protocol number 50 replace the source IP address of the

IPSec gateway to the routers WAN IP address However SUA should not

change the source port of the UDP packets which are used for key

managements Because the remote gateway checks this source port during

connections the port thus is not allowed to be changed



14


SUA

For outgoing IPSec tunnels no extra setting is required

For forwarding the inbound IPSec ESP tunnel A Default server set is required

You could configure it in Web Configurator Advanced Setup Network -gt NAT

-gt Port Forwarding -gt Default Server Setup

It is because SUA makes your LAN appear as a single machine to the outside

world LAN users are invisible to outside users So to make an internal server

for outside access we must specify the service port and the LAN IP of this

server in Web configurator Thus SUA is able to forward the incoming packets

to the requested service behind SUA and the outside users access the server

using the P-660HW-Dx v2s WAN IP address So we have to configure the

internal IPsec client as a default server (unspecified service port) when it acts

a server gateway

14 What is Traffic Shaping

Traffic Shaping allocates the bandwidth to WAN dynamically and aims at

boosting the efficiency of the bandwidth If there are serveral VCs in the

P-660HW-Dx v2 but only one VC activated at one time the P-660HW-Dx v2

allocates all the Bandwidth to the VC and the VC gets full bandwidth If another

VCs are activated later the bandwidth is yield to other VCs after ward

15 Why do we perform traffic shaping in the P-660HW-Dx v2

The P-660HW-Dx v2 must manage traffic fairly and provide bandwidth

allocation for different sorts of applications such as voice video and data All

applications have their own natural bit rate Large data transactions have a

fluctuating natural bit rate The P-660HW-Dx v2 is able to support variable

traffic among different virtual connections Certain traffic may be discarded if

the virtual connection experiences congestion Traffic shaping defines a set of

actions taken by the P-660HW-Dx v2 to avoid congestion traffic shaping takes



15

measures to adapt to unpredictable fluctuations in traffic flows and other

problems among virtual connections

16 What do the parameters (PCR SCR MBS) mean

Traffic shaping parameters (PCR SCR MBS) can be set in Web Configurator

Advanced Setup Network -gt Remote Node -gt Edit -gt ATM Setup

Peak Cell Rate(PCR) The maximum bandwidth allocated to this connection

The VC connection throughput is limited by PCR

Sustainable Cell Rate(SCR) The least guaranteed bandwidth of a VC

When there are multi-VCs on the same line the VC throughput is guaranteed

by SCR

Maximum Burst Size(MBS) The amount of cells transmitted through this

VC at the Peak Cell Rate before yielding to other VCs Total bandwidth of the

line is dedicated to single VC if there is only one VC on the line However as

the other VC asking the bandwidth the MBS defines the maximum number of

cells transmitted via this VC with Peak Cell rate before yielding to other VCs

The P-660HW-Dx v2 holds the parameters for shaping the traffic among its

virtual channels If you do not need traffic shaping please set SCR = 0 MBS =

0 and PCR as the maximum value according to the line rate (for example 23

Mbps line rate will result PCR as 5424 cellsec)


Constant bit rate(CBR) An ATM bandwidth-allocation service that requires

the user to determine a fixed bandwidth requirement at the time the connection

is set up so that the data can be sent in a steady stream CBR service is often

used when transmitting fixed-rate uncompressed video

Unspecified bit rate(UBR) An ATM bandwidth-allocation service that does

not guarantee any throughput levels and uses only available bandwidth UBR

is often used when transmitting data that can tolerate delays such as e-mail

Variable bit rate(VBR) An ATM bandwidth-allocation service that allows

users to specify a throughput capacity (ie a peak rate) and a sustained rate

but data is not sent evenly You can select VBR for bursty traffic and

bandwidth sharing with other applications It contains two subclasses

Variable bit rate nonreal time (VBR-nRT)

Variable bit rate real time (VBR-RT)

18 What is content filter



16

Internet Content filter allows you to create and enforce Internet access policies

tailored to your needs Content filter gives you the ability to block web sites that

contain key words (that you specify) in the URL You can set a schedule for

when the P-660HW-Dx v2 performs content filtering You can also specify

trusted IP Addresses on LAN for which the P-660HW-Dx v2 will not perform

content filtering You can configure the details about it in Web Configurator

ADSL FAQ

1 How does ADSL compare to Cable modems

ADSL provides a dedicated service over a single telephone line cable

modems offer a dedicated service over a shared media While cable modems

have greater downstream bandwidth capabilities (up to 30 Mbps) that

bandwidth is shared among all users on a line and will therefore vary perhaps

dramatically as more users in a neighborhood get online at the same time

Cable modem upstream traffic will in many cases be slower than ADSL either

because the particular cable modem is inherently slower or because of rate

reductions caused by contention for upstream bandwidth slots The big

difference between ADSL and cable modems however is the number of lines

available to each There are no more than 12 million homes passed today that

can support two-way cable modem transmissions and while the figure also

grows steadily it will not catch up with telephone lines for many years

Additionally many of the older cable networks are not capable of offering a

return channel consequently such networks will need significant upgrading

before they can offer high bandwidth services

2 What is the expected throughput

In our test we can get about 16Mbps data rate on 15Kft using the 26AWG

loop The shorter the loop the better the throughput is

3 What is the microfilter used for






4 How do I know the ADSL line is up

You can see the DSL LED Green on the P-660HW-Dx v2s front panel is on

when the ADSL physical layer is up

5 How does the P-660HW-Dx v2 work on a noisy ADSL

Depending on the line quality the P-660HW-Dx v2 uses Fall Back and Fall

Forward to automatically adjust the date rate

multiplexing

Though the LLC-based multiplexing can carry multiple protocols over a single

VC it requires extra header information to identify the protocol being carried

on the virtual circuit (VC) The VC-based multiplexing needs a separate VC for

carrying each protocol but it does not need the extra headers Therefore the

VC-based multiplexing is more efficient

7 How do I know the details of my ADSL line statistics

You can use the following CI commands to check the ADSL line

statistics

CIgt wan adsl perfdata

CIgt wan adsl status

CIgt wan adsl linedata far

CIgt wan adsl linedata near

You can also do it in Web Configurator Advanced Setup

Maintenance -gt Diagnostic -gt DSL Line -gt DSL Status

8 What are the signaling pins of the ADSL connector

The signaling pins on the P-660HW-Dx v2s ADSL connector are pin 3 and pin

4 The middle two pins for a RJ11 cable

9 What is triple play



19

More and more TelcoISPs are providing three kinds of services (VoIP Video

and Internet) over one existing ADSL connection

The different services (such as video VoIP and Internet access) require

different Qulity of Service

The high priority is Voice (VoIP) data

The Medium priority is Video (IPTV) data

The low priority is internet access such as ftp etc hellip

Triple Play is a port-based policy to forward packets from different LAN port to

different PVCs thus you can configure each PVC separately to assign different

QoS to different application

Firewall FAQ

General

1 What is a network firewall

A firewall is a system or group of systems that enforces an access-control

policy between two networks It may also be defined as a mechanism used to

protect a trusted network from an untrusted network The firewall can be

thought of two mechanisms One to block the traffic and the other to permit

traffic

2 What makes P-660HW-Dx v2 secure

The P-660HW-Dx v2 is pre-configured to automatically detect and thwart

Denial of Service (DoS) attacks such as Ping of Death SYN Flood LAND

attack IP Spoofing etc It also uses stateful packet inspection to determine if

an inbound connection is allowed through the firewall to the private LAN The

P-660HW-Dx v2 supports Network Address Translation (NAT) which

translates the private local addresses to one or multiple public addresses This

adds a level of security since the clients on the private LAN are invisible to the

Internet

3 What are the basic types of firewalls

Conceptually there are three types of firewalls

1 Packet Filtering Firewall

2 Application-level Firewall

3 Stateful Inspection Firewall

Packet Filtering Firewalls generally make their decisions based on the header

information in individual packets These headers information include the

source destination addresses and ports of the packets

Application-level Firewalls generally are hosts running proxy servers which

permit no traffic directly between networks and which perform logging and

auditing of traffic passing through them A proxy server is an application

gateway or circuit-level gateway that runs on top of general operating system

such as UNIX or Windows NT It hides valuable data by requiring users to

communicate with secure systems by mean of a proxy A key drawback of this

device is performance



21

Stateful Inspection Firewalls restrict access by screening data packets against

defined access rules They make access control decisions based on IP

address and protocol They also inspect the session data to assure the

integrity of the connection and to adapt to dynamic protocols The flexible

nature of Stateful Inspection firewalls generally provides the best speed and

transparency however they may lack the granular application level access

control or caching that some proxies support

4 What kind of firewall is the P-660HW-Dx v2

1 The P-660HW-Dx v2s firewall inspects packets contents and IP

headers It is applicable to all protocols that understands data in the

packet is intended for other layers from network layer up to the

application layer

2 The P-660HW-Dx v2s firewall performs stateful inspection It takes into

account the state of connections it handles so that for example a

legitimate incoming packet can be matched with the outbound request

for that packet and allowed in Conversely an incoming packet

masquerading as a response to a nonexistent outbound request can be

blocked

3 The P-660HW-Dx v2s firewall uses session filtering ie smart rules

that enhance the filtering process and control the network session

rather than control individual packets in a session

4 The P-660HW-Dx v2s firewall is fast It uses a hashing function to

search the matched session cache instead of going through every

individual rule for a packet

5 The P-660HW-Dx v2s firewall provides email service to notify you for

routine reports and when alerts occur

5 Why do you need a firewall when your router has packet filtering and

NAT built-in

With the spectacular growth of the Internet and online access companies that

do business on the Internet face greater security threats Although packet filter

and NAT restrict access to particular computers and networks however for

the other companies this security may be insufficient because packets filters

typically cannot maintain session state Thus for greater security a firewall is

considered

6 What is Denials of Service (DoS) attack

Denial of Service (DoS) attacks are aimed at devices and networks with a

connection to the Internet Their goal is not to steal information but to disable

a device or network so users no longer have access to network resources



22

There are four types of DoS attacks

1 Those that exploits bugs in a TCPIP implementation such as Ping of

Death and Teardrop

2 Those that exploits weaknesses in the TCPIP specification such as

SYN Flood and LAND Attacks

3 Brute-force attacks that flood a network with useless data such as

Smurf attack

4 IP Spoofing

7 What is Ping of Death attack

Ping of Death uses a PING utility to create an IP packet that exceeds the

maximum 65535 bytes of data allowed by the IP specification The oversize

packet is then sent to an unsuspecting system Systems may crash hang or

reboot

8 What is Teardrop attack

Teardrop attack exploits weakness in the reassemble of the IP packet

fragments As data is transmitted through a network IP packets are often

broken up into smaller chunks Each fragment looks like the original packet

except that it contains an offset field The Teardrop program creates a series of

IP fragments with overlapping offset fields When these fragments are

reassembled at the destination some systems will crash hang or reboot

9 What is SYN Flood attack

SYN attack floods a targeted system with a series of SYN packets Each

packet causes the targeted system to issue a SYN-ACK response While the

targeted system waits for the ACK that follows the SYN-ACK it queues up all

outstanding SYN-ACK responses on what is known as a backlog queue

SYN-ACKs are moved off the queue only when an ACK comes back or when

an internal timer (which is set a relatively long intervals) terminates the TCP

three-way handshake Once the queue is full the system will ignore all

incoming SYN requests making the system unavailable for legitimate users

10 What is LAND attack

In a LAN attack hackers flood SYN packets to the network with a spoofed

source IP address of the targeted system This makes it appear as if the host

computer sent the packets to itself making the system unavailable while the

target system tries to respond to itself



23

11 What is Brute-force attack

A Brute-force attack such as Smurf attack targets a feature in the IP

specification known as directed or subnet broadcasting to quickly flood the

target network with useless data A Smurf hacker flood a destination IP

address of each packet is the broadcast address of the network the router will

broadcast the ICMP echo request packet to all hosts on the network If there

are numerous hosts this will create a large amount of ICMP echo request

packet the resulting ICMP traffic will not only clog up the intermediary

network but will also congest the network of the spoofed source IP address

known as the victim network This flood of broadcast traffic consumes all

available bandwidth making communications impossible

12 What is IP Spoofing attack

Many DoS attacks also use IP Spoofing as part of their attack IP Spoofing

may be used to break into systems to hide the hackers identity or to magnify

the effect of the DoS attack IP Spoofing is a technique used to gain

unauthorized access to computers by tricking a router or firewall into thinking

that the communications are coming from within the trusted network To

engage in IP Spoofing a hacker must modify the packet headers so that it

appears that the packets originate from a trusted host and should be allowed

through the router or firewall


There are two default ACLs pre-configured in the P-660HW-Dx v2 one allows

all connections from LAN to WAN and the other blocks all connections from

WAN to LAN except of the DHCP packets

Configuration

1 How do I configure the firewall

You can use the Web Configurator to configure the firewall for P-660HW-Dx v2

By factory default if you connect your PC to the LAN Interface of P-660HW-Dx

Log and Alert

1 When does the P-660HW-Dx v2 generate the firewall log

The P-660HW-Dx v2 generates the firewall log immediately when the packet

matches a firewall rule The log for Default Firewall Policy (LAN to WAN WAN

to LAN WAN to WAN) is generated automatically with factory default setting

but you can change it in Web Configurator

2 What does the log show to us

The log supports up to 128 entries There are 5 columns for each entry Please

see the example shown below

3 How do I view the firewall log

All logs generated in P-660HW-Dx v2 including firewall logs IPSec logs

system logs are migrated to centralized logs So you can view firewall logs in

Centralized logs Web Configurator Advanced setup Maintenance -gt Logs

-gtView Log

The log keeps 128 entries the new entries will overwrite the old entries when

the log has over 128 entries

Before you can view firewall logs there are two steps you need to do

(1) Enable log function in Centralized logs setup via either one of the following

methods

Wireless FAQ

General FAQ

1 What is a Wireless LAN

Wireless LANs provide all the functionality of wired LANs without the need for

physical connections (wires) Data is modulated onto a radio frequency carrier

and transmitted through the ether Typical bit-rates are 11Mbps and 54Mbps

although in practice data throughput is half of this Wireless LANs can be

formed simply by equipping PCs with wireless NICs If connectivity to a wired

LAN is required an Access Point (AP) is used as a bridging device APs are

typically located close to the centre of the wireless client population

2 What are the advantages of Wireless LAN

Mobility Wireless LAN systems can provide LAN users with access to

real-time information anywhere in their organization This mobility supports

productivity and service opportunities not possible with wired networks

Installation Speed and Simplicity Installing a wireless LAN system can be

fast and easy and can eliminate the need to pull cable through walls and

ceilings

Installation Flexibility Wireless technology allows the network to go where

wire cannot go

Reduced Cost-of-Ownership While the initial investment required for

wireless LAN hardware can be higher than the cost of wired LAN hardware

overall installation expenses and life-cycle costs can be significantly lower

Long-term cost benefits are greatest in dynamic environments requiring

frequent moves and changes

Scalability Wireless LAN systems can be configured in a variety of topologies

to meet the needs of specific applications and installations Configurations are

easily changed and range from peer-to-peer networks suitable for a small

number of users to full infrastructure networks of thousands of users that

enable roaming over a broad area

3 What is the disadvantage of Wireless LAN

The speed of Wireless LAN is still relatively slower than wired LAN The setup

cost of Wireless LAN is relative high because the equipment cost including

access point and PCMCIA Wireless LAN card is higher than hubs and CAT 5

cables



29

4 Where can you find 80211 wireless networks

Airports hotels and even coffee shops like Starbucks are deploying 80211

networks so people can wirelessly surf the Internet with their laptops

5 What is an Access Point

The AP (access point also known as a base station) is the wireless server that

with an antenna and a wired Ethernet connection that broadcasts information

using radio signals AP typically acts as a bridge for the clients It can pass

information to wireless LAN cards that have been installed in computers or

laptops allowing those computers to connect to the campus network and the

Internet without wires

6 Whatrsquos the difference between IEEE80211abg

The IEEE 80211 is a wireless LAN industry standard and the objective of

IEEE 80211 is to make sure that different manufactures wireless LAN devices

can communicate to each other Below is a brief comparison for the

IEEE80211 abg

Yes As long as the products comply to the same IEEE 80211 standard The

Wi-Fi logo is used to define 80211b compatible products Wi-Fi5 is a

compatibility standard for 80211a products running in the 5GHz band

8 What is Wi-Fi

The Wi-Fi logo signifies that a product is interoperable with wireless

networking equipment from other vendors A Wi-Fi logo product has been

tested and certified by the Wireless Ethernet Compatibility Alliance (WECA)

The Socket Wireless LAN Card is Wi-Fi certified and that means that it will

work (interoperate) with any brand of Access Point that is also Wi-Fi certified

9 What types of devices use the 24GHz Band

Various spread spectrum radio communication applications use the 24 GHz

band This includes WLAN systems (not necessarily of the type IEEE



30

80211b) cordless phones wireless medical telemetry equipment and

Bluetoothtrade short-range wireless applications which include connecting

printers to computers and connecting modems or hands-free kits to mobile

phones

10 Does the 80211 interfere with Bluetooth device

Any time devices are operated in the same frequency band there is the

potential for interference

Both the 80211bg and Bluetooth devices occupy the same24-to-2483-GHz

unlicensed frequency range-the same band But a Bluetooth device would not

interfere with other 80211 devices much more than another 80211 device

would interefere While more collisions are possible with the introduction of a

Bluetooth device they are also possible with the introduction of another 80211

device or a new 24 GHz cordless phone for that matter But BlueTooth

devices are usually low-power so the effects that a Bluetooth device may have

on an 80211 network if any arent far-reaching

11 Can radio signals pass through wall

Transmitting through a wall is possible depending upon the material used in its

construction In general metals and substances with a high water content do

not allow radio waves to pass through Metals reflect radio waves and concrete

attenuates radio waves The amount of attenuation suffered in passing through

concrete will be a function of its thickness and amount of metal re-enforcement

used

12 What are potential factors that may causes interference among WLAN

products

Factors of interference

(1) Obstacles walls ceilings furniturehellip etc

(2) Building Materials metal door aluminum studs

(3) Electrical devices microwaves monitors electric motors

Solution

(1) Minimizing the number of walls and ceilings

(2) Antenna is positioned for best reception

(3) Keep WLAN products away from electrical devices eg microwaves

monitors electric motorshellip etc

(4) Add additional APs if necessary

13 Whats the difference between a WLAN and a WWAN

WLANs are generally privately owned wireless systems that are deployed in a

corporation warehouse hospital or educational campus setting Data rates

are high and there are no per-packet charges for data transmission

WWANs are generally publicly shared data networks designed to provide

coverage in metropolitan areas and along traffic corridors WWANs are owned

by a service provider or carrier Data rates are low and charges are based on



31

usage Specialized applications are characteristically designed around short

burst messaging

14 Can I manually swap the wireless module without damage any

hardware

Yes it will not harm the hardware but the module will not be detected and

work after inserting to the slot You need to reboot the router to initialize the

module


The wireless security modes supported on P-660HW-Dx v2 are Static

WEP WPA-PSK WPA WPA2-PSK and WPA2

16 What Wireless standard does P-660HW-Dx v2 support

It supports IEEE 80211bgg+ standard

17 Does P-660HW-Dx v2 support MAC filtering

Yes it supports up to 32 MAC Address filtering

18 Does P-660HW-Dx v2 support auto rate adaption

Yes it means that the AP on P-660HW-Dx v2 will automatically decelerate

when devices move beyond the optimal range or other interference is present

If the device moves back within the range of a higher-speed transmission the

connection will automatically speed up again Rate shifting is a physical-layer

mechanism transparent to the user and the upper layers of the protocol stack

Advanced FAQ

1 What is Ad Hoc mode

A wireless network consists of a number of stations without using an access

point or any connection to a wired network

2 What is Infrastructure mode

Infrastructure mode implies connectivity to a wired communications

infrastructure If such connectivity is required the Access Points must be used

to connect to the wired LAN backbone Wireless clients have their

configurations set for infrastructure mode in order to utilise access points

relaying

3 How many Access Points are required in a given area

This depends on the surrounding terrain the diameter of the client population

and the number of clients If an area is large with dispersed pockets of

populations then extension points can be used for extend coverage



32

4 What is Direct-Sequence Spread Spectrum Technology ndash (DSSS)

DSSS spreads its signal continuously over a wide frequency band DSSS

maps the information bearing bit-pattern at the sending station into a higher

data rate bit sequence using a chipping code The chipping code (also known

as processing gain) introduces redundancy which allows data recovery if

certain bit errors occur during transmission The FCC rules the minimum

processing gain should be 10 typical systems use processing gains of 20

IEEE 80211b specifies the use of DSSS

5 What is Frequency-hopping Spread Spectrum Technology ndash (FHSS)

FHSS uses a narrowband carrier which hops through a predefined sequence

of several frequencies at a specific rate This avoids problems with fixed

channel narrowband noise and simple jamming Both transmitter and receiver

must have their hopping sequences synchronized to create the effect of a

single logical channel To an unsynchronised receiver an FHSS transmission

appears to be short-duration impulse noise 80211 may use FHSS or DSSS


No Provided the antenna is optimally designed for 24GHz or 5GHz operation

WLAN NICs often include an internal antenna which may provide sufficient

reception

7 Why the 24 GHZ Frequency range

This frequency range has been set aside by the FCC and is generally labeled

the ISM band A few years ago Apple and several other large corporations

requested that the FCC allow the development of wireless networks within this

frequency range What we have today is a protocol and system that allows for

unlicensed use of radios within a prescribed power level The ISM band is

populated by Industrial Scientific and Medical devices that are all low power

devices but can interfere with each other

8 What is Server Set ID (SSID)

SSID is a configurable identification that allows clients to communicate to the

appropriate base station With proper configuration only clients that are

configured with the same SSID can communicate with base stations having

the same SSID SSID from a security point of view acts as a simple single

shared password between base stations and clients

9 What is an ESSID

ESSID stands for Extended Service Set Identifier and identifies the wireless

LAN The ESSID of the mobile device must match the ESSID of the AP to

communicate with the AP The ESSID is a 32-character maximum string and is

case-sensitive

Security FAQ



33

1 How do I secure the data across the P-660HW-Dx v2 Access Points

radio link

To secure the date across the P-660HW-Dx v2 Access Point‟s radio link we

could select any one of the security mode Static 64128256 bit WEP

WPA-PSK WPA WPA2-PSK WPA2

2 What is WEP

Wired Equivalent Privacy WEP is a security mechanism defined within the

80211 standard and designed to make the security of the wireless medium

equal to that of a cable (wire) WEP data encryption was designed to prevent

access to the network by intruders and to prevent the capture of wireless

LAN traffic through eavesdropping WEP allows the administrator to define a

set of respective Keys for each wireless network user based on a Key

String passed through the WEP encryption algorithm Access is denied by

anyone who does not have an assigned key Note WEP has shown to have

fundamental flaws in its key generation processing

3 What is WPA

Wi-Fi Protected Access (WPA) is a subset of the IEEE 80211i security

specification draft Key differences between WAP and WEP are user

authentication and improved data encryption WAP applies IEEE 8021x

Extensible Authentication Protocol (EAP) to authenticate wireless clients using

an external RADIUS database You can not use the P-660HW-Dx v2s local

user database for WPA authentication purpose since the local user database

uses MD5 EAP which can not to generate keys

WPA improves data encryption by using Temporal Key Integrity Protocol

(TKIP) Message Integrity Check and IEEE 8021x Temporal Key Integrity

Protocol uses 128-bits keys that are dynamically generated and distributed by

the authentication server It includes a per-packet key mixing function a

Message Integrity Check (MIC) named Michael an extend initialization vector

(IV) with sequencing rules and a re-keying mechanism

If you do not have an external RADIUS server you should use WPA-PSK

(WPA Pre-Share Key) that only requires a single (identical) password entered

into each access point wireless gateway and wireless client As long as the

passwords match a client will be granted access to a WLAN You can refer to

the User Guide for more information about it

4 What is the difference between 40-bit and 64-bit WEP

40 bit WEP and 64 bit WEP are the same encryption level and can interoperate

The lower level of WEP encryption uses a 40 bit (10 Hex character) as secret

key (set by user) and a 24 bit Initialization Vector (not under user control)



34

(40+24=64) Some vendors refer to this level of WEP as 40 bit others as 64

bit

5 What is a WEP key

A WEP key is a user defined string of characters used to encrypt and decrypt

data

6 Will 128-bit WEP communicate with 64-bit WEP

No 128-bit WEP will not communicate with 64-bit WEP Although 128 bit WEP

also uses a 24 bit Initialization Vector but it uses a 104 bit as secret key Users

need to use the same encryption level in order to make a connection

7 Can the SSID be encrypted

No WEP only encrypts the data packets not the 80211 management

packetsThe SSID is in the beacon and probe management messages and

SSID goes over the air in clear text This makes obtaining the SSID easy by

sniffing 80211 wireless traffic

8 By turning off the broadcast of SSID can someone still sniff the SSID

Many APs by default have broadcasting the SSID turned on Sniffers typically

will find the SSID in the broadcast beacon packets Turning off the broadcast of

SSID in the beacon message (a common practice) does not prevent getting

the SSID since the SSID is sent in the clear in the probe message when a

client associates to an AP a sniffer just has to wait for a valid user to associate

to the network to see the SSID

9 What are Insertion Attacks

The insertion attacks are based on placing unauthorized devices on the

wireless network without going through a security process and review

10 What is Wireless Sniffer

An attacker can sniff and capture legitimate traffic Many of the sniffer tools for

Ethernet are based on capturing the first part of the connection session where

the data would typically include the username and password An intruder can

masquerade as that user by using this captured information An intruder who

monitors the wireless network can apply this same attack principle on the

wireless

11 What is OTIST How do I use it

OTIST is acronym for ZyXEL‟s bdquoOne Touch Intelligent Security Technology‟

It enables P-660HW-Dx v2 and ZyXEL‟s OTIST supported Wireless adapters

to establish connections of the WPA-PSK security mode automatically with

just one touch at the reset button on rear panel



35

To use this function on P-660HW-Dx v2 you could press the reset button on

P-660HW-Dx v2 for 1~5 seconds the OTIST is actived The P-660HW-Dx v2

will enhance the Wireless Security Level to WPA-PSK automatically if no

WLAN security has been set The default setup key for OTIST is bdquo01234567‟

Application Notes

General Application Notes

1 Internet Access Using P-660HW-Dx v2 under Bridge mode

Setup your workstation

Setup your P-660HW-Dx v2 under bridge mode

If the ISP limits some specific computers to access Internet that means only

the traffic tofrom these computers will be forwarded and the other will be

filtered In this case we use P-660HW-Dx v2 which works as an ADSL bridge

modem to connect to the ISP The ISP will generally give one Internet account

and limit only one computer to access the Internet

Set up your workstation

(1) Ethernet connection

To connect your computer to the P-660HW-Dx v2s LAN port the computer

must have an Ethernet adapter card installed For connecting a single

computer to the P-660HW-Dx v2 we use a Ethernet cable

(2) TCPIP configuration

In most cases the IP address of the computer is assigned by the ISP

dynamically so you have to configure the computer as a DHCP client which

obtains the IP from the ISP using DHCP protocol The ISP may also provide

the gateway DNS via DHCP if they are available Otherwise please enter the

static IP addresses for all that the ISP gives to you in the network TCPIP

settings For Windows we check the option Obtain an IP address

automatically in its TCPIP setup please see the example shown below



37


The following procedure shows you how to configure your P-660HW-Dx v2 as

bridge mode We will use Web Configurator to guide you through the related

menu

(1) Configure P-660HW-Dx v2 as bridge mode and configure Internet setup

parameters in Web Configurator Advanced Setup Network -gt WAN -gt

Specify a VPI (Virtual Path Identifier) and a VCI (Virtual Channel

Identifier) given to you by your ISP

(2) Turn off DHCP Server and configure a LAN IP for the P-660HW-Dx v2 in

Web Configurator Advanced Setup Network -gt LAN We use 19216811 as

the LAN IP for P-660HW-Dx v2 in this case

Step 1 Disactive DHCP Server and apply it

Step 2 Assign an IP to the LAN Interface of P-660HW-Dx v2 eg

19216811



account for Internet access they have to install an Internet sharing device like

a router In this case we use the P-660HW-Dx v2 which works as a general




Connect the LAN ports of all computers to the LAN Interface of P-660HW-Dx

v2 using Ethernet cable


Since the P-660HW-Dx v2 is set to DHCP server as default so you need only

to configure the workstations as the DHCP clients in the networking settings In

this case the IP address of the computer is assigned by the P-660HW-Dx v2

The P-660HW-Dx v2 can also provide the DNS to the clients via DHCP if it is

available For this setup in Windows we check the option Obtain an IP

address automatically in its TCPIP setup Please see the example shown

What is DHCP Relay

DHCP stands for Dynamic Host Configuration Protocol In addition to the

DHCP server feature the P-660HW-Dx v2 supports the DHCP relay function

When it is configured as DHCP server it assigns the IP addresses to the LAN

clients When it is configured as DHCP relay it is responsible for forwarding

the requests and responses negotiating between the DHCP clients and the

server See figure 1

Setup the P-660HW-Dx v2 as a DHCP Relay

We could set the P-660HW-Dx v2 as a DHCP Relay by the following command

in CLI

Ip dhcp enif0 mode relay

Introduction

Generally SUA makes your LAN appear as a single machine to the outside

world LAN users are invisible to outside users However some applications

such as Cu-SeeMe and ICQ will need to connect to the local user behind the

P-660HW-Dx v2 In such case a SUA server must be configured to forward

the incoming packets to the true destination behind SUA After the required

server are configured in Web Configurator Advanced Setup Network -gt NAT

Configure an Internal Server behind SUA

Introduction

If you wish you can make internal servers (eg Web ftp or mail server)

accessible for outside users even though SUA makes your LAN appear as a

single machine to the outside world A service is identified by the port number

Also since you need to specify the IP address of a server behind the

P-660HW-Dx v2 a server must have a fixed IP address and not be a DHCP

client whose IP address potentially changes each time P-660HW-Dx v2 is

powered on

In addition to the servers for specific services SUA supports a default server

A service request that does not have a server explicitly designated for is

forwarded to the default server If the default server is not defined the service

request is simply discarded

Configure a PPTP server behind SUA

Introduction

PPTP is a tunneling protocol defined by the PPTP forum that allows PPP

packets to be encapsulated within Internet Protocol (IP) packets and

forwarded over any IP network including the Internet itself

In order to run the Windows 9x PPTP client you must be able to establish an

IP connection with a tunnel server such as the Windows NT Server 40

Remote Access Server

Windows Dial-Up Networking uses the Internet standard Point-to-Point (PPP)

to provide a secure optimized multiple-protocol network connection over

dial-up telephone lines All data sent over this connection can be encrypted

and compressed and multiple network level protocols (TCPIP NetBEUI and

IPX) can be run correctly Windows NT Domain Login level security is

preserved even across the Internet



47

Window98 PPTP Client Internet NT RAS Server Protocol Stack

PPTP appears as new modem type (Virtual Private Networking Adapter) that

can be selected when setting up a connection in the Dial-Up Networking folder

The VPN Adapter type does not appear elsewhere in the system Since PPTP

encapsulates its data stream in the PPP protocol the VPN requires a second

dial-up adapter This second dial-up adapter for VPN is added during the

installation phase of the Upgrade in addition to the first dial-up adapter that

provides PPP support for the analog or ISDN modem

The PPTP is supported in Windows NT and Windows 98 already For

Windows 95 it needs to be upgraded by the Dial-Up Networking 12 upgrade

Configuration

This application note explains how to establish a PPTP connection with a

remote private network in the P-660HW-Dx v2 SUA case In ZyNOS all PPTP

packets can be forwarded to the internal PPTP Server (WinNT server) behind

SUA The port number of the PPTP has to be entered in the Web

Configurator Advanced Setup Network -gt NAT -gt Port Forwarding on

P-660HW-Dx v2 to forward to the appropriate private IP address of Windows

NT server



48

Example

The following example shows how to dial to an ISP via the P-660HW-Dx v2

and then establish a tunnel to a private network There will be three items that

you need to set up for PPTP application these are PPTP server (WinNT)

PPTP client (Win9x) and the P-660HW-Dx v2

(1) PPTP server setup (WinNT)

Add the VPN service from Control Panel -gtNetwork

Add an user account for PPTP logged on user

Enable RAS port

Select the network protocols from RAS such as IPX TCPIP NetBEUI

Set the Internet gateway to P-660HW-Dx v2

(2) PPTP client setup (Win9x)

Add one VPN connection from Dial-Up Networking by entering the

correct username amp password and the IP address of the P-660HW-Dx

v2s Internet IP address for logging to NT RAS server

Set the Internet gateway to the router that is connecting to ISP

(3) P-660HW-Dx v2 setup

Before making a VPN connection from Win9x to WinNT server you

need to connect P-660HW-Dx v2 router to your ISP first

Enter the IP address of the PPTP server (WinNT server) and the

port number for PPTP as shown below



49

Select service name as bdquoPPTP‟ fill in the Server IP Address then press button

bdquoAdd‟

When you have finished the above settings you can ping to the remote Win9x

client from WinNT This ping command is used to demonstrate that remote

the Win9x can be reached across the Internet If the Internet connection

between two LANs is achievable you can place a VPN call from the remote

Win9x client

For example Cping 203661132

When a dial-up connection to ISP is established a default gateway is assigned

to the router traffic through that connection Therefore the output below shows

the default gateway of the Win9x client after the dial-up connection has been

established

Before making a VPN connection from the Win9x client to the NT server you

need to know the exact Internet IP address that the ISP assigns to

P-660HW-Dx v2 router in SUA mode and enter this IP address in the VPN

dial-up dialog box You can check this Internet IP address from PNC Monitor or

S Web Configurator Status -gt WAN Information If the Internet IP address

is a fixed IP address provided by ISP in SUA mode then you can always use

this IP address for reaching the VPN server

In the following example the IP address 1401131225 is dynamically

assigned by ISP You must enter this IP address in the VPN Server dialog box

for reaching the PPTP server After the VPN link is established you can start

the network protocol application such as IP IPX and NetBEUI

NAT Server Sets

The NAT Server Set is a list of LAN side servers mapped to external ports

(similar to the old SUA menu of before) If you wish you can make inside

servers for different services eg Web or FTP visible to the outside users

even though NAT makes your network appears as a single machine to the

outside world A server is identified by the port number eg Web service is on

port 80 and FTP on port 21

As an example (see the following figure) if you have a Web server at

192168136 and a FTP server at 192168133 then you need to specify for

port 80 (Web) the server at IP address 192168136 and for port 21 (FTP)

another at IP address 192168133



56

Please note that a server can support more than one service eg a server

can provide both FTP and Mail service while another provides only Web

service

Examples

Internet Access Only

Internet Access with an Internal Server

Using Multiple Global IP addresses for clients and servers

Support Non NAT Friendly Applications

(1) Internet Access Only

In our Internet Access example we only need one rule where all our ILAs map

to one IGA assigned by the ISP You can just use the default SUA NAT or you



57

could select Full Feature NAT and select an Address Mapping Set with a

Many-to-One Rule See the following figure

(2) Internet Access with an Internal Server

In this case we do exactly as the figure (use the convenient pre-configured

SUA Only set) and also go to Web Configurator Advanced Setup Network -gt

NAT -gt Port Forwarding to specify the Internet Server behind the NAT as



58

below

(3) Using Multiple Global IP addresses for clients and servers

(One-to-One Many-to-One Server Set mapping types are used)

In this case we have 3 IGAs from the ISP We have two very busy internal FTP

servers and also an internal general server for the web and mail In this case

we want to assign the 3 IGAs by the following way using 4 NAT rules

Rule 1 (One-to-One type) to map the FTP Server 1 with ILA1

(192168110) to IGA1 (200001)


(192168111) to IGA2 (200002)

Rule 3 (Many-to-One type) to map the other clients to IGA3 (200003)

Rule 4 (Server type) to map a web server and mail server with ILA3

(192168120) to IGA3 Type Server allows us to specify multiple

servers of different types to other machines behind NAT on the LAN



59

Step 1 In this case we need to map ILA to more than one IGA therefore we

must choose the Full Feature option from the NAT field in currently active

remote node and assign IGA3 to P-660HW-Dx v2‟s WAN IP Address

Step 2 Go to Web Configurator Advanced Setup Network -gt NAT -gt

Address Mapping to begin configuring Address Mapping Set 1 We can see

there are 10 blank rule table that could be configured See the following setup

for the four rules in our case

Rule 1 Setup Select One-to-One type to map the FTP Server 1 with ILA1

(192168110) to IGA1 (200001)

Rule 2 Setup Selecting One-to-One type to map the FTP Server 2 with ILA2

(192168111) to IGA2 (200002)



60

Rule 3 Setup Select Many-to-One type to map the other clients to IGA3

(200003)

Rule 4 Setup Select Server type to map our web server and mail server with

ILA3 (192168120) to IGA3

Menu Network -gt NAT -gt Address Mapping should look as follows now



61

Step 3 Now we configure all other incoming traffic to go to our web server and

mail server from Web Configurator Advanced Setup Network -gt NAT -gt Port

Forwarding

(4) Support Non NAT Friendly Applications

Some servers providing Internet applications such as some mIRC servers do

not allow users to login using the same IP address In this case it is better to

use Many-to-Many No Overload or One-to-One NAT mapping types thus each

user login to the server using a unique global IP address The following figure

illustrates this



62

One rule configured for using Many-to-Many No Overload mapping type is

shown below

We can also do this by configure threeOne-to-One mapping type rules

6 Using the Dynamic DNS (DDNS)

What is DDNS

The DDNS service an IP Registry provides a public central database where

information such as email addresses hostnames IPs etc can be stored and

retrieved This solves the problems if your DNS server uses an IP associated

with dynamic IPs


P-660HW-Dx v2 to access the internal server It is inconvenient for the users if






must inform the DDNS server the change of this IP so that the server can



63

update its IP-to-DNS entry Once the IP-to-DNS table in the DDNS server is

updated the DNS name for your web server (ie wwwzyxelcomtw) is still

usable

The DDNS servers the P-660HW-Dx v2 supports currently is

WWWDYNDNSORG where you apply the DNS from and update the WAN IP

to

Setup the DDNS

1 Before configuring the DDNS settings in the P-660HW-Dx v2 you must

register an account from the DDNS server such as

WWWDYNDNSORG first After the registration you have a hostname

for your internal server and a password using to update the IP to the

DDNS server

2 Login Web Configurator Advanced Setup Advanced -gt Dynamic DNS

Select Active Dynamic DNS option

Key Settings

Option Description

Service Provider Enter the DDNS server in this field Currently we support

WWWDYNDNSORG

Active Toggle to Yes

Host Name Enter the hostname you subscribe from the above DDNS server

For example zyxelcomtw

User Name Enter the user name that the DDNS server gives to you



64

Password Enter the password that the DDNS server gives to you

Enable Wildcard

Enter the hostname for the wildcard function that the

WWWDYNDNSORG supports Note that Wildcard option is

available only when the provider is httpwwwdyndnsorg

7 Network Management Using SNMP

ZyXEL SNMP Implementation

ZyXEL currently includes SNMP support in some P-660HW-Dx v2 routers It is

implemented based on the SNMPv1 so it will be able to communicate with

SNMPv1 NMSs Further users can also add ZyXELs private MIB in the NMS

to monitor and control additional system variables The ZyXELs private MIB

tree is shown in figure 3 For SNMPv1 operation ZyXEL permits one

community string so that the router can belong to only one community and

allows trap messages to be sent to only one NMS manager

Some traps are sent to the SNMP manager when anyone of the following

events happens

1 coldStart (defined in RFC-1215)

If the machine coldstarts the trap will be sent after booting

2 warmStart (defined in RFC-1215)

If the machine warmstarts the trap will be sent after booting

3 linkDown (defined in RFC-1215)

If any link of IDSL or WAN is down the trap will be sent with the port

number The port number is its interface index under the interface

group

4 linkUp (defined in RFC-1215)

If any link of IDSL or WAN is up the trap will be sent with the port


group

5 authenticationFailure (defined in RFC-1215)

When receiving any SNMP get or set requirement with wrong community

this trap is sent to the manager



65

6 whyReboot (defined in ZYXEL-MIB)

When the system is going to restart (warmstart) the trap will be sent with the

reason of restart before rebooting

(1) For intentional reboot

In some cases (download new files CI command sys reboot ) reboot is

done intentionally And traps with the message System reboot by user will

be sent

(2) For fatal error

System has to reboot for some fatal errors And traps with the message of the

fatal code will be sent

9 Using IP Alias

What is IP Alias

In a typical environment a LAN router is required to connect two local

networks The P-660HW-Dx v2 can connect three local networks to the ISP or

a remote node we call this function as IP Alias In this case an internal

router is not required For example the network manager can divide the local

network into three networks and connect them to the Internet using

P-660HW-Dx v2s single user account See the figure below



68

The P-660HW-Dx v2 supports three virtual LAN interfaces via its single

physical Ethernet interface The first network can be configured in Web

Configurator Advanced Setup Network -gt LAN -gt DHCP Setup The second

and third networks that we call IP Alias 1 and IP Alias 2 can be configured

in Network -gt LAN -gt IP Alias

There are three internal virtual LAN interfaces for the P-660HW-Dx v2 to route

the packets fromto the three networks correctly They are enif0 for the major

network enif00 for the IP alias 1 and enif01 for the IP alias 2 Therefore

three routes are created in the P-660HW-Dx v2 as shown below when the

three networks are configured If the P-660HW-Dx v2s DHCP is also enabled

the IP pool for the clients can be any of the three networks



69

You can edit filter rule to accept or deny LAN packets fromto the IP alias 12

go through the P-660HW-Dx v2 by command in CLI

lan index [index number]

Usage index number =1 main LAN

2 IP Alias1

3 IP Alias2

will create the second route in the enif00 interface

IP Alias 2 Active it and enter the third LAN IP address for the P-660HW-Dx v2 This

will create the third route in the enif01 interface

10 Using IP Policy Routing

What is IP Policy Routing (IPPR)

Traditionally routing is based on the destination address only and the router

takes the shortest path to forward a packet IP Policy Routing (IPPR) provides

a mechanism to override the default routing behavior and alter the packet

forwarding based on the policy defined by the network administrator

Policy-based routing is applied to incoming packets on a per interface basis

prior to the normal routing Network administrators can use IPPR to distribute



70

traffic among multiple paths For example if a network has both the Internet

and remote node connections we can route the Web packets to the Internet

using one policy and route the FTP packets to the remote LAN using another

policy See the figure below

Use IPPR to distribute traffic among multiple paths

Benefits

Source-Based Routing - Network administrators can use policy-based

routing to direct traffic from different users through different connections

Quality of Service (QoS)- Organizations can differentiate traffic by setting the

precedence or TOS (Type of Service) values in the IP header at the periphery

of the network to enable the backbone to prioritize traffic

Cost Savings- IPPR allows organizations to distribute interactive traffic on

high-bandwidth high-cost path while using low-path for batch traffic

Load Sharing- Network administrators can use IPPR to distribute traffic

among multiple paths

How does the IPPR work

A policy defines the matching criteria and the action to take when a packet

meets the criteria The action is taken only when all the criteria are met The

criteria include the source address and port IP protocol (ICMP UDP TCP

etc) destination address and port TOS and precedence (fields in the IP

header) and length The inclusion of length criterion is to differentiate between

interactive and bulk traffic Interactive applications eg Telnet tend to have

short packets while bulk traffic eg file transfer tends to have large packets



71

The actions that can be taken include routing the packet to a different gateway

(and hence the outgoing interface) and the TOS and precedence fields in the

IP header IPPR follows the existing packet filtering facility of ZyNOS in style

and in implementation The policies are divided into sets where related

policies are grouped together A use defines the policies before applying them

to an interface or a remote node in the same fashion as the filters There are

12 policy sets with 6 policies in each set

Setup the IP Policy Routing

Setp 1 Set the index of IP routing policy set rule by command bdquoip

policyrouting set index [set] [rule]‟ Suppose set=1 rule=1 in this

example

Step 2 Suppose we‟d like to edit the rule like this

Policy Set Name=Test

Active= Yes

Criteria

IP Protocol = 6

Type of Service= Dont Care Packet length= 0

Precedence = Dont Care Len Comp= NA

Source

addr start= 19216812 end= 192168120

port start= 0 end= NA

Destination

addr start= 0000 end= NA

port start= 80 end= 80

Action= Matched

Gateway addr = 1921681254 Log= No

Type of Service= No Change

Precedence = No Change

This policy example forces the Web packets originated from the clients with IP

addresses from 19216812 to 192168120 be routed to the remote LAN via

the gateway 1921681254

To implement this we need to invoke the following command one by one

ip policyrouting set name Test

(Set the name as Test of IP routing policy rule )

ip policyrouting set active yes

(Enable the rule)

ip policyrouting set criteria protocol 6

(Set the protocol ID as 6(TCP) for the rule)



72

ip policyrouting set criteria serviceType 0

(Set the criteria type of service as don‟t care for this rule)

ip policyrouting set criteria precedence 8

(Set the precedence as don‟t care for this rule)

ip policyrouting set criteria packetlength 0

(Set the packet length as 0 for the rule)

ip policyrouting set criteria srcip 19216812 192168120

(Set the source IP address for the rule Start=19216812 end=192168120)

ip policyrouting set criteria srcport 0

(Set the source port for the rule Start=0)

ip policyrouting set criteria destip 0000

(Set the destination port for the rule Start=0000)

ip policyrouting set criteria destport 80 80

(Set the destination port for the rule Start=80 end=80)

ip policyrouting set action actmatched

(Set the action for the rule Matched)

ip policyrouting set action gatewaytype 0

(Set gateway type for the rule Gateway Address)

ip policyrouting set action gatewayaddr 1921681254

(Set the gateway address for the rule 1921681254)


(Set the action type of service as don‟t care for this rule)


(Set the action precedence as don‟t care for this rule)

ip policyrouting set action log no

(Set log option for the rule no log)

ip polictrouting set save

(Save the rule)

Step 3 Apply the IP policy routing There are two interfaces to apply the policy

set they are the LAN interface and WAN interface It depends where the

gateway specified in the policy rule is located If the gateway you specified is

located on the local LAN you apply the policy set in LAN interface If the

gateway you specified is located on the remote WAN site you apply the policy

set in WAN interface

Apply to WAN Interface (Suppose we apply it to remote node 1 in the

example)

wan node index 1

wan node ippolicy 1

11 Using Call Scheduling

What is Call Scheduling



73

Call scheduling enables the mechanism for the P-660HW-Dx v2 to run the

remote node connection according to the pre-defined schedule This feature is

just like the scheduler in a video recorder which records the program according

to the specified time Users can apply at most 4 schedule sets in Remote Node

The remote node configured with the schedule set could be Forced On

Forced Down Enable Dial-On-Demand or Disable Dial-On-Demand on

specified date and time

How to configure a Call Scheduling

You can configure a call scheduling in CLI

Suppose we want to edit a call schedule set like this

Call Schedule Set =1

Set name=Test

Active= Yes

Start Date(yyyy-mm-dd)= 2005 - 12 - 27

How Often= Once

Once

Date(yyyy-mm-dd)= 2005 -12 -27

Start Time(hhmm)= 12 00

Duration(hhmm)= 16 00

Action= Enable Dial-on-demand

This schedule example permits a demand call on the line on 1200 am

2005-12-27 The maximum length of time this connection is allowed is 16

hours


wan callsch index 1

(Set call schedule index = 1 You must apply this command first before you

begin to configure call schedule)

wan callsch name Test

(Set the schedule name as Test)

wan callsch active Yes

(Enable schedule)

wan callsch startdate 2005 12 27

(Set schedule start date as 2005-12-27)

wan callsch oncedate 2005 12 27

(Set the schedule used just once it works on 2005-12-27)

wan callsch starttime 12 00

(Set the schedule start time as 1200)



74

wan callsch duration 16 00

(Set schedule duration time as 16 hours)

wan callsch action 2

(Set action as dial-on-demand)

wan callsch save

(Save the current call schedule set)

Key Settings

Start Date

Start date of this schedule rule It can be unmatched with weekday

setting For example if Start Date is 20001002(Monday) but Monday

setting in weekday can be No

Forced On The node will always keep up during the setting period It is equivalent

to diable the idel timeout

Forced Down The node will always keep doen during the setting period The

connected remote node will be dropped

Enable

Dial-On-Demand The remote node accepts Dial-on-demand during this period

Disable

Dial-On-Demand

The remote node denies any demand dial during the period For the

existing connected nodes it will be dropped after idle timeout and no

triggered up

Start Time

Duration Start Time and Duration of this schedule

Apply the schedule to the Remote node

Multiple scheduling rules can program in a Remote node and they have

priority For example if we program the sets as 1234 in remote node then

the set 1 will override set 234 set 2 will override 34 and so on

We can apply the schedule to the remote node in CLI by the commands

wan node index []index]

wan node callsch [index]

wan node save

For example if we want to apply the call schedule set 1 to remote node 1 we

could use the commands

wan node index 1

wan node callsch 1

wan node save

Time Service in P-660HW-Dx v2

There is no RTC (Real-Time Clock) chip so the P-660HW-Dx v2 should launch

a mechanism to get current time and date from external server in boot time



75

Time service is implemented by the Daytime protocol(RFC-867) Time

protocol(RFC-868) and NTP protocol(RFC-1305) You have to assign an IP

address of a time server and then the P-660HW-Dx v2 will get the date time

and time-zone information from this server You can configure it in Web

Configurator Advanced Setup Maintenance -gt System -gt Time Setting

12 Using IP Multicast

What is IP Multicast

Traditionally IP packets are transmitted in two ways - unicast or broadcast

Multicast is a third way to deliver IP packets to a group of hosts Host groups

are identified by class D IP addresses ie those with 1110 as their

higher-order bits In dotted decimal notation host group addresses range from

224000 to 239255255255 Among them 224001 is assigned to the

permanent IP hosts group and 224002 is assigned to the multicast routers

group

IGMP (Internet Group Management Protocol) is the protocol used to support

multicast groups The latest version is version 2 (see RFC2236) IP hosts use

IGMP to report their multicast group membership to any immediate-neighbor

multicast routers so the multicast routers can decide if a multicast packet

needs to be forwarded At start up the P-660HW-Dx v2 queries all directly

connected networks to gather group membership

After that the P-660HW-Dx v2 updates the information by periodic queries

The P-660HW-Dx v2 implementation of IGMP is also compatible with version 1

The multicast setting can be turned on or off on Ethernet and remote nodes

13 Using Bandwidth Management

Why Bandwidth Management (BWM)

Nowadays we have many different traffic types for Internet applications Some

traffic may consume high bandwidth such as FTP (File Transfer Protocol)

Some other traffic may not require high bandwidth but they require stable

supply of bandwidth such as VoIP traffic The VoIP quality would not be good

if all of the outgoing bandwidth is occupied via FTP Additionally chances are

that you would like to grant higher bandwidth for somebody special who is

using specific IP address in your network All of these are reasons why we

need bandwidth management

Using BWM

Setp 1 Go to Web Configurator Advanced Setup Advanced -gt Bandwidth

MGMT-gtSummary activate bandwidth management on the interface you

would like to manage We enable the BWM function on WAN interface in this

example

Enter the total speed for this interface that you want to allocate using

bandwidth management This appears as the bandwidth budget of the

interface‟s root class

Select how you want the bandwidth to be allocated Priority-Based means

bandwidth is allocated via priority so the traffic with highest priority would be

served first then the second priority is served secondly and so on If

Fairness-Based is chosen then the bandwidth is allocated by ratio Which

means if A class needs 300 kbps B class needs 600 kbps then the ratio of A

and Bs actual bandwidth is 12 So if we get 450 kbps in total then A would

get 150 kbps B would get 300 kbps We select Priority-Based in this

example



77

Key Settings

Active

Check the box to enable BWM on the interface Note that if you would like

to manage traffic from WAN to LAN you should apply BWM on LAN

interface If you would like to management traffic from WAN to DMZ

please apply BWM on DMZ interface

Speed Enter the total speed to manage on this interface This value is the budget

of the class trees root

Scheduler

Choose the principle to allocate bandwidth on this interface

Priority-Based allocates bandwidth via priority Fairness-Based allocates

bandwidth by ratio

Maximize

Usage

Check this box if you would like to give residuary bandwidth from Interface

to the classes who need more bandwidth than configured amount Do not

select this if you want to reserve bandwidth for traffic that does not match a

bandwidth class or you want to limit the bandwidth of each class at the

configured value (Please note that to meat the second condition you

should also disable Use All Managed Bandwidth in the BWM rule)

Step 2 Go to Web Configurator Advanced Setup Advanced -gt Bandwidth

MGMT-gt Rule Setup select the interface Service Priority and Allocated

14 Using Zero-Configuration

Zero-Configuration and VC auto-hunting

Zero-Configure feature can help customer to reduce the burden of setting

efforts Whenever system ADSL links up system will send out some probing

patterns system will analyze the packets returned from ISP and decide which

services the ISP may provide Because ADSL is based on a ATM network so

system have to pre-configured a VPIVCI hunting pool before Auto-Configure

function begins to work

The Zero-Configuration feature can hunt the encapsulation and VPIVCI value

and system will automatically configure itself if the hunting result is

successfully This feature has two constraints

1 It supports the ISP provides one kind of service (PPPoEPPPoA etc)

only otherwise the hunting will get confusing and failed

2 VC auto-hunting only supports dynamic WAN IP address If the router is

set a static WAN IP address VC auto-hunting function will be disabled

The entry of hunting pool must also contain the VPI VCI and which kinds of

hunting patterns you wish to send Whenever system send out all the probing

patterns with specific VPIVCI system will wait for 5~10 seconds and get the

response from ISP the response patterns will decide which kinds of ADSL

services of the line will be After that system will save back the correct VPI

VCI and also services (encapsulation) type into profile of WAN interface

Configure the VC auto-hunting preconfigured table

(1) Display auto-haunting preconfigured table by using command from CLI

wan atm vchunt display



80

(2) Add items to the auto-haunting preconfigured table by using commands

wan atm vchunt add ltremoteNodeIndexgt ltvpigt ltvcigt ltservice

bit(hex)gt

wan atm vchunt save

Note ltremote nodegt input the remote node index 1-8

ltvpigt vpi value

ltvcigt vci value

ltservicegt it‟s a hex value bit0PPPoEVC (1) bit1PPPoELLC (2)

bit2PPPoAVC (4) bit3PPPoALLC (8) bit4EnetVC (16) bit5 EnetLLC (32)

For example

(1) If you need service PPPoELLC and EnetLLC then the service bits will be

2+32 = 34 (decimal) = 22 (hex) you must input 22

(2) If you want to enable all service for VC hunting the service bits will be

1+2+4+8+16+32=63(decimal)= 3f (hex) you must input 3f

Need to perform save after this by command bdquowan atm vchunt save‟

(3) Delete items from the auto-haunting preconfigured table by useing

command

wan atm vchunt remove ltremote nodegt ltvpigt ltvcigt



81

Using Zero configuration

You can enabledisable Zero Configuration in Network -gt WAN -gt Advanced

Setup

(1) After configure the auto-haunting preconfigured table You just need a PC

connected to the device LAN Ethernet port with the DSL sync up

(2) Open your web browser to access a Web site It should prompt and request

for your username password of your ISP account if your ISP provide PPPoE

or PPPoA service

(3) After key-in the correct info it will than test the connection If it is

successful it will than close the browser and you can open a new browser to

surf the Internet If the connection test fail it will go back to the page ask for

user name and password

(4) Basically the zero configuration only work on the VC that was preconigured

in the auto-haunting preconfigured table

15 How could I configure triple play on P-660HW-Dx v2

The common triple play scenario is as follows



82


different PVCs thus we could assign different parameters to the PVC (CBR

UBR VBR-RT VBR-nRT) to guarantee different applications

We could configure triple play on P-660HW-Dx v2 via CLI The command is

sys tripleplay set portbase ltEportIDgt ltPVCIDgt

For example sys tripleplay portbase set 1 1

sys tripleplay portbase set 2 2


The traffic from Ethernet port 1 must be forwarded to PVC1 vice versa


The traffic from Ethernet Port3 must be forwarded to PVC3 vice versa

16 How to configure packet filter on P-660HW-Dx v2

The P-660HW-Dx v2 allows you to configure up to twelve filter sets with six

rules in each set for a total of 72 filter rules in the system You can apply up to

four filter sets to a particular port to block multiple types of packets With each

filter set having up to six rules you can have a maximum of 24 rules active for

a single port

The packet filter function on P-660HW-Dx v2 is the same as before just that

you could only configure the filter set and apply them by command in CLI It‟s

very complex for common users to do it So here‟s the recommendation

(1) Usually if you want to block special packets you could edit a firewall rule in

Wireless Application Notes

1 Configure a Wireless Client to Ad hoc mode

Ad hoc Introduction

What is Ad Hoc mode

Ad hoc mode is a wireless network consists of a number of stations without

access points Without using an access point or any connection to a wired

network a client unit in Ad hoc operation mode can communicate directly to

other client units just as using a cross over Ethernet cable connecting 2 hosts

together via a NIC card for direct connection when configured in Ad hoc mode

without an access point being present Ad hoc operation is ideal for small

networks of no more than 2-4 computers Larger networks would require the

use of one or perhaps several access points

Configuration for Wireless Station A

To configure Ad hoc mode on your ZyAIR B-100B-200B-300 wireless NIC

cards please follow the following step

Step 1 Double click on the utility icon in your windows task bar the utility will

Infrastructure Mode

3 MAC Filter

MAC Filter Overview

Users can use MAC Filter as a method to restrict unauthorized stations from

accessing the APs ZyXELs APs provide the capability for checking MAC

address of the station before allowing it to connect to the network This

provides an additional layer of control layer in that only stations with registered

MAC addresses can connect This approach requires that the list of MAC

addresses be configured



95

ZyXEL MAC Filter Implementation

ZyXELs MAC Filter Implementation allows users to define a list to allow or

block association from STAs The filter set allows users to input 12 entries in

the list If Allow Association is selected all other STAs which are not on the list

will be denied Otherwise if Deny Association is selected all other STAs which

are not on the list will be allowed for association Users can choose either way

to configure their filter rule

4 Setup WEP (Wired Equivalent Privacy)

Introduction

The 80211 standard describes the communication that occurs in wireless

LANs

The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless

communication from eavesdropping because wireless transmissions are

easier to intercept than transmissions over wired networks and wireless is a

shared medium everything that is transmitted or received over a wireless

network can be intercepted

WEP relies on a secret key that is shared between a mobile station (eg a

laptop with a wireless Ethernet card) and an access point (ie a base station)

The secret key is used to encrypt packets before they are transmitted and an

integrity check is used to ensure that packages are not modified during the

transition The standard does not discuss how the shared key is established In

practice most installations use a single key that is shared between all mobile

stations and access points APs You can refer to the User Guide for more

detailed information about it

Setting up the Access Point

You can set up the Access Point from Web configurator Advanced Setup

Network -gt Wireless LAN -gt General (You can also configure it via CLI)

Step 1 Select bdquoStatic WEP‟ from the pull down menu bdquoSecurity Mode‟ in Web

Configurator



97

Step 2 Set up WEP Key in the Web Configurator You need to set the one of

the following parameters

o 64-bit WEP key (secret key) with 5 characters

o 64-bit WEP key (secret key) with 10 hexadecimal digits





There are two ways you can configure the WEP Key

(1) You can put in a special WEP key in the bdquoWEP Key‟ menu directly



98

(2) You can also put in an arbitrary sequence of characters in the

bdquoPassphrase‟ and then press button bdquoGenerate‟ to let the P-660HW-Dx v2

generate WEP Key for you

Setting up the Station

Step 1 Double click on the utility icon in your windows task bar or right click

the utility icon then select Show Config Utility



99

The utility will pop up on your windows screen

Note If the utility icon doesnt exist in your task bar click Start -gt

Programs -gt helliphellip to start the utility

Step 2 Select the Configuration tab

Select bdquoSet Security‟ to configure encryption type and parameters

correspond with access point



100

Note You should select Key 1 as default Transmit Key since the P-660HW-Dx

v2 is supposed to use Key 1 by default

Key settings

The WEP Encryption type of station has to equal to the access point

Check ASCII field for characters WEP key or uncheck ASCII field for

Hexadecimal digits WEP key



101

Hexadecimal digits dont need to precede by 0x

For example

64-bits with characters WEP key Key1= 2e3f4

64-bits with hexadecimal digits WEP key Key1= 123456789A

5 Site Survey

Introduction

What is Site Survey

An RF site survey is a MAP to RF contour of RF coverage in a particular

facility With wireless system it is very difficult to predict the propagation of

radio waves and detect the presence of interfering signals Walls doors

elevator shafts and other obstacles offer different degree of attenuation This

will cause the RF coverage pattern be irregular and hard to predict

Site survey can help us overcome these problem and even provide us a map

of RF coverage of the facility

Preparation

Below are the steps to complete a simple site survey with simple tools

1 First you will need to obtain a facility diagram such as blueprints This is

for you to mark and take record on

2 Visually inspect the facility walk through the facility to verify the accuracy of

the diagram and mark down any large obstacle you see that may effect the RF

signal such as metal shelf metal desk etc on the diagram

3 Identify users area when doing so ask a question where is wireless

coverage needed and where does not and note and take note on the diagram

this is information is needed to determine the number of AP required

4 Determine the preliminary access point location on the facility diagram base

on the service area needed obstacles power wall jack considerations

Survey on Site

Step 1 With the diagram with all information you gathered in the preparation

phase Now you are ready to make the survey



102

Step 2 Install an access point at the preliminary location

Step 3 Use a notebook with wireless client installed and run its utility An utility

will provide information such as connection speed current used channel

associated rate link quality signal strength and etc information as shown in

utility below

Step 4 Its always a good idea to start with putting the access point at the

corner of the room and walk away from the access point in a systematic

manner Record the changes at point where transfer rate drop and the link

quality and signal strength information on the diagram as you go alone



103

Step 5 When you reach the farthest point of connection mark the spot Now

you move the access point to this new spot as have already determine the

farthest point of the access point installation spot if wireless service is required

from corner of the room

Step 6 Repeat step 1~5 and now you should be able to mark an RF coverage

area as illustrated in above picutre

Step 7 You may need more than one access point is the RF coverage area

hasn‟t covered all the wireless service area you needed

Step 8 Repeat step 1~6 of survey on site as necessary upon completion you

will have a diagram and information of site survey As illustrated below



104

Note If there are more than one access point is needed be sure to make the

adjacent access point service area over lap one another So the wireless

station is able to roam For more information please refer to roaming at
